Video height 属性

❮ Video 对象

实例

改变视频的高度:

document.getElementById("myVideo").height = "500";
亲自试一试 »

定义和用法

height 属性设置或返回视频的height属性值。

height 属性指定视频的高度,以像素为单位。

提示:始终指定视频的高度和宽度属性。 如果设置了高度和宽度,则在加载页面时保留视频所需的空间。 但是,如果没有这些属性,浏览器就无法知道视频的大小,也无法为其预留合适的空间。 效果将是页面布局将在加载期间(视频加载时)发生变化。

注意:不要使用高度和宽度属性重新缩放视频! 缩小具有高度和宽度属性的大型视频会迫使用户下载原始视频(即使它在页面上看起来很小)。 重新缩放视频的正确方法是使用程序,然后再在页面上使用它。
